You can find a Raptor Egg on the west bank of the river between Nymph Lake and the Oracle Caves - these raptors only appear when you have the ranger quests.
The Werewolf is to be found on the west side of the Shire - around the area where Jathil wanders looking for the graveyard.
There are two sets of samurai skeletons - to get the baton, enter the castle moat on the east side, swim pass the first towers and get out. There is an inlet in the woods there - you will see gravestones and a chest as well.
You do not need to bring Grunaxe's ring back to anyone.
The "dragon machine" is the Dragon Spire, not the Stout Mines. The Stout Mines are to the south. Visit them before Dragon Spire!
